Uranium (U) Summary Statistics

Uranium averaged 1.59 ppm (± 1.35 ppm) in West Virginia coals
with a histogram showing a near normal distribution with a tail toward
higher values. The highest U contents were all from the Sewickley
coal and range from 10.09 to 17.12 ppm. Uranium correlated very poorly
with ash yield, and poorly with tellurium (Te), bismuth (Bi), samarium
(Sm), scandium (Sc), thorium (Th) and praseodymium (Pr).
